Week 1: Invalid Syntax

[ashraf21c]

Hello,
This code returns an "Invalid Syntax" error.

`REPLACE_BY_SPACE_RE = re.compile('[/(){}[]|@,;]')
BAD_SYMBOLS_RE = re.compile('[^0-9a-z #+_]')
STOPWORDS = set(stopwords.words('english'))

def text_prepare(text):
"""
text: a string

    return: modified initial string
"""
text = # lowercase text
text = # replace REPLACE_BY_SPACE_RE symbols by space in text
text = # delete symbols which are in BAD_SYMBOLS_RE from text
text = # delete stopwords from text
return text`

The problem is in this specific line of code:

text = # lowercase text

I found the solution at course`s forum.
